Value Collection 261015 Aircraft Extension Drill Bit 15/64

Product Description

The VALUE COLLECTION 261015 is a carbide-tipped aircraft extension drill bit designed for deep-reach drilling in metal and composite materials. Built to Series 2610 standards, this bit measures 15/64 inch (0.2344 inch decimal) in diameter with a 2-5/8 inch flute length and a 6 inch overall length. The 135-degree split point is self-centering and web-thinned, reducing walking and entry force on hard materials. The bright, uncoated finish suits general-purpose applications where coating is not required. Licensed trades and industrial machinists working in aerospace, HVAC ductwork, and structural fabrication rely on this style of bit for accurate, extended-reach holes.

This drill bit is suited for applications where standard-length bits cannot reach the work surface, such as drilling through structural members, deep box sections, or layered panel assemblies. The straight-cylindrical shank seats securely in standard drill chucks. The right-hand spiral flute clears chips efficiently during through-hole drilling in steel, aluminum, and similar materials. General-purpose performance makes it a practical addition to service kits for field technicians and shop machinists alike.

Key Features

• Carbide-tipped cutting edge for extended tool life in metal and composite drilling
• 135-degree split point with web thinning for self-centering starts and reduced thrust
• 6 inch overall length with 2-5/8 inch flute length for extended-reach access
• Straight-cylindrical shank compatible with standard drill chucks
• Right-hand, two-flute spiral design for efficient chip evacuation
• Bright, uncoated finish for general-purpose use across common metals

Compatibility

Designed as an OEM-style general-purpose aircraft extension drill bit suitable for use in standard keyed or keyless drill chucks accepting a 15/64 inch straight-cylindrical shank, conforming to NAS 907 standards.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and trade professionals using corded or pneumatic drill equipment. Secure the straight-cylindrical shank firmly in the chuck before use and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid when drilling ferrous materials to manage heat and extend tip life. Inspect the carbide tip for chipping or wear before each use, as carbide tips are brittle and can fail under side-load or impact.
